Using sampling concepts, it is found that this is an example of independent samples.
For dependent samples, there is a paired measurement for one set of items.
For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.
In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.
